Blastcrete Equipment Co. recently introduced the D3522 attachment, a hot epoxy pump that can be powered by an existing hydraulic power source. It is lighter, more versatile and more affordable than hot epoxy pumps and mixer/pump combinations with built-in power supplies, especially since skid steers and other equipment with auxiliary hydraulic hookups can power the unit.
Featuring a hydraulic squeeze (peristaltic) pump built for long life and low total cost of ownership, it has two rollers that rotate clockwise and squeeze a 2-inch rubber pumping tube. The rotation generates suction from the receiving hopper and pushes the material through the pump and out the discharge into the delivery hose. The epoxy materials do not come in contact with the moving parts of the squeeze pump, unlike a rotor stator or piston-style pump. The attachment’s primary wear part, a 2-inch rubber pumping tube, can be replaced in 20 minutes or less.
The attachment can pump hot epoxy or cementitious grouts at variable speeds from 0 to 6 cubic yards per hour and deliver up to 400 psi of pumping pressure. Those capabilities, coupled with the unit’s light weight, make it easy to transport and highly versatile. Contractors can use the pump for a wide variety of applications, such as grouting to mount and secure heavy industrial equipment and pumping fiberglass jackets for pier rehabilitation and stabilization. The D3522 attachment also can be used for spraying plaster and small wet-shotcrete applications.
